The main role of aluminum sulfate
The main role of aluminum sulfate
Aluminum sulfate is made by decomposing alumite with sulfuric acid, or by pressurizing reaction between bauxite soil and sulfuric acid. It has the properties of being extremely soluble in water, white, odorless, and hygroscopic. According to its characteristics, which fields can it be used in Well, let's take a look at its main function with the editor below.
Aluminum sulfate is a widely used industrial reagent and is often confused with alum. Alum is a double salt of aluminum sulfate and potassium sulfate, while aluminum sulfate is a single salt. Double salt, also known as weight salt, is composed of two or more mono-salts, which ionize into mono-salt ions in solution. Aluminum sulfate is usually used as a flocculant for the purification of drinking water and sewage treatment equipment, and it is also used in the paper industry. Under natural conditions, aluminum sulfate hardly exists in the form of anhydrous salt. It will form a series of hydrates, among which aluminum sulfate hexadecahydrate is common. Aluminum sulfate is also a very effective mollusk insecticide, which can kill Spanish slugs. Aluminum sulfate is used for water purification and as a medium in the printing and dyeing of textiles. In water purification, it condenses impurities, making it easier to settle and filter. When dissolved in a large amount of neutral or slightly alkaline water, it produces colloidal precipitated aluminum hydroxide. When printing and dyeing cloth, the aluminum hydroxide colloid makes it easier for the dye to adhere to the plant fiber. Aluminum sulfate is also used to adjust the pH of the soil because it hydrolyzes to produce aluminum hydroxide while producing a small amount of dilute sulfuric acid solution.
Aluminum sulfate is mainly used in papermaking and used as a flocculant in water. These two are the main functions. At the same time, it is also very common in the fire protection industry. It can also be used as a raw material for medicine, alum, etc.
